Abstract

Natural bioactives are an excellent source of carotenoids for the production of nutraceuticals, functional foods and food additives. The extraction efficiencies of solid-liquid extraction (SLE), supercritical CO2, supercritical CO2 with ethanol as co-solvent for the recovery of the carotenoids, xanthophyll and fucoxanthin, from two brown macroalgae Fucus serratus and Laminaria digitata were explored. The extraction efficiency was measured using both purity and yield of target compounds. Solid liquid extraction (hexane/acetone (70:30) at 50°C for 24h produced the greatest yield of carotenoid rich extracts from F. serratus. Optimal conditions in terms of carotenoid yield using supercritical CO2 were 50°C, 300Atm with an extraction time of 60min. SCO2 yielded a higher purity of fucoxanthin while SLE resulted in a higher purity of xanthophyll. Seasonal/spatial variation based on the purity and yield was also investigated to provide valuable information on optimal harvest time for these compounds.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Carotenoids are natural antioxidants applied in food products; the most abundant carotenoid of marine macroalgae is fucoxanthin, which possesses antiproliferative activity; carotenoids also possess antioxidant, antimicrobial, and antihypertensive activity.

    “Carotenoids are natural antioxidants and they are applied in different food products [18]. The most abundant carotenoid of marine macroalgae is fucoxanthin (Figure 4) and it possess antiproliferative activity [19,20]. Except for antiproliferative properties, carotenoids also possess antioxidant [21], antimicrobial, and antihypertensive activity [22].”
  • Conditions during extraction, especially pressure and temperature, are responsible for selectivity and solubility of various compounds in supercritical fluid.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
